SPECIFICATION forming part Of Letters Patent N0. 731,281, dated June 16,1903.

Application filed June 13, 1902. Serial No. 111,485. (No model.)

Means for Repairing Rubber Boots or Shoes,

of which the following is a full, clear, and exact description.

Our invention relates to means for repairing rubber boots and shoes, andthe object that we have in view is the provision of a simple andinexpensive apparatus by which a new; rubber sole may be expeditiouslyapplied to the upper of a boot or shoe or a rubber patch may bevulcanized on a worn boot or shoe at the heel or sole thereof, the newsole applied by our apparatus having a roughened or crrugated bottomsurface, whereby repairs may be effected at a small cost and the ownersaved the expense of purchasing new boots or shoes.

A further object of the invention is the provision of a mold having aproper pattern-surface to give the corrugated face to the bottom catecorresponding parts in all the figures.

Figure 1 is a view in side elevation, partly broken away and in section,of an apparatus for repairing rubber boots and shoes constructed inaccordance with our invention. Fig. 2 is a sectional plan viewthereof onthe line 2 2 in Fig. 1, and Fig. 3 is a detail longitudinal sectionthrough the mold and the pressure-plate, illustrating a piece of workthereon.

5 designates the shell or casing of the improved vulcanizer, the samebeing provided with suitable legs 6 for supporting it in an uprightposition. This shell or casing is chambered, as at 7, and said casing isopen at the upper side in order to accommodate the removable mold 8.This mold is provided with a mold-cavity 9,'which is bounded orsurrounded by a substantially upright wall hav ing the contour of thesole which it is desired to supply to a boot or shoe. The mold is alsoprovided'with a marginal flange or rim 10, that is adapted to rest uponthe top edge of the casing 5, and in this flange or rim is a series ofvent-openings 11, which, if desired, may be temporarily closed by anysuitable means. The presence of the mold-cavity 9 forms or provides adepending portion on the under side of the mold, and said mold is ar=ranged to restupon or be secured to the casing 5 in a position to closethe open top portion thereof, thus arranging the depending portion ofthe mold in the chamber 7 of the casing, whereby the heat is free tocirculate around and in contact with the entire under surface of themold.

12 designates a heating-pipe which is ar ranged in a horizontal positionwithin the chamber 7 of the casing, said pipe having a series ofoutlet-openings 13 in its upper side. Aportion of this heating-pipeprojects through the casing and is provided with a stop-cock 14. Aflexible tube or hose 15 is coupled to the projecting end of the pipe,and hot air or other heating medium may be supplied fuse the heatuniformly within the chamber 7.

One of the important features of our invention is the mold 8, having acorrugated active face 9 011 the bottom of the depression or mold-cavityJ. This corrugated surface is intended to impart to the sole a roughenedappearance, thus making the new rubber sole closely simulate or followan ornamentation which is given to the boot or shoe sole at the time ofits manufacture. In our invention the mold is economically manufacturedby casting on a chilled surface having the desired pattern which givesthe corrugated appearance to the active face, as indicated at 9 in Fig.2. Obviously the pattern-surface 9 cannot be produced in the mold-cavityby cutting the same by hand or milling the same by machinery withoutmaking the mold quite costly of manufacture; but by casting the mold ona chilled surface we are able to materially reduce the cost of makingthe same.

17 designates an upright which is flanged, as at 18, and fitted againstan end portion of the casing 5, said flanged part of the upright beingfirmly secured to the casing by the screws or bolts 19. The upright hasan overhanging arm 19, in which is provided a threaded opening adaptedto accommodate the threaded pressure-screw 20, the latter having asuitable crank-handle 21 for its convenient manipulation.

22 designates a pressure-post which is provided at its upper end with anarm 23 and at its lower end with a foot-piece 24. The foot of thispressure-postis adapted to he slipped into the upper of a boot or shoewhich it is desired to repair, and said foot portion of the postcooperates with a pressure-plate 25, the latter being arranged to liewithin the boot or shoe and to partly occupy the mold-cavity 9. Thepressure-plate 25 may be attached to the post 22 or it may be made in aseparate piece, and this pressure-plate is intended to cooperate withthe mold and the post in order to secure proper pressure on the rubberfor repairing the boot or shoe. The pressureplate should conformsomewhat to the size of the mold-cavity, and we may em ploypressureplates of different sizes. It is evident that molds havingdifferent-size cavities may be used in connection with the chamberedcasing of the vulcanizer for the purpose of repairing boots or shoes ofdifferent styles and sizes.

26 designates a scale-plate adapted to support a suitable thermometer, apart of which is indicated at 27 in Fig. 1, said thermometer having itsbulb exposed to the heat that circulates in the chamber 7 of the casing.

In repairing a rubber boot the worn sole is removed from the upper andthe latter is thoroughly cleaned by any suitable agent. The mold S isplaced 011 the chambered casing 5 and the proper quantity of soft rubberis placed on the boot or shoe, which is then fitted in the mold-cavityin order to extend over the pattern-surface 9. The post 22 and itsfoot-piece 24, together with the pressureplate, are fitted in the bootor shoe at the proper time. The parts are placed on or in the mold insuch a way that the edge portion of the boot or shoe upper and therubber sole will be received in the mold-cavity, after which the screw20 is operated so as to apply the pressure to the post 22. The pressureof the post and of the plate 25, which lies below the post, spreads therubber uniformly throughout the mold-cavity and secures a sole which isuniform in thickness, and finally the heat is admitted to the pipe 12and difiused by the baffle-plate 16 through the chamber of the casing,thus vulcanizing the rubber sole to the boot or shoe upper, said solepartaking of the pattern-surface 9 of the moldcavity. A rubber shoe orboot may be re paired at the heel or sole portion by using a mold havinga proper configuration.

Having thus described our invention, we claim as new and desire tosecure by Letters Patent In an apparatus of the class described, thecombination with a mold, means for heating the mold, and an elevatedclamping-screw, of a pressure-plate consisting of a single thickness andconforming approximately to the shape of a boot or shoe sole, and apressure-post having an angular foot-piece at its lower end and a headat its upper end, said plate and the foot-piece of the post beinginsertible into a boot or shoe for the foot-piece to rest on the plate,and the clamping-screw being arranged to exert pressure on the post byengaging with the head thereof.

In testimony whereof we have signed our names to this specification inthe presence of two subscribing witnesses.
